Global Regulatory Mandates as Drivers for Advanced Chemical Analysis in Food Safety

Area of Science:

• Food Safety and Analytical Chemistry
• Regulatory Science
• Global Food Supply Chain Analysis

Background:

• Globalization of food supply chains creates complex safety assurance challenges within fragmented regulatory environments.
• Existing legal mandates significantly influence the development and application of analytical chemistry techniques.
• Divergent toxicological philosophies and dietary exposure models contribute to global regulatory heterogeneity.

Purpose of the Study:

• To synthesize and evaluate regulatory frameworks from eight influential jurisdictions (EU, US, China, Codex Alimentarius).
• To assess how legal mandates act as drivers for analytical chemistry evolution in food safety.
• To identify limitations of current analytical methods and propose future directions.

Main Methods:

• Comparative analysis of legal mandates, including Maximum Residue Limits (MRLs) and positive list systems.
• Examination of method validation guidelines (e.g., SANTE) across different jurisdictions.
• Review of analytical techniques, focusing on the establishment of LC/GC-MS/MS for multi-residue screening.

Main Results:

• Strict preventive controls have standardized chromatography coupled with tandem mass spectrometry (LC/GC-MS/MS) for multi-residue screening.
• Regulatory fragmentation necessitates analytical laboratories to maintain 'defensive technological redundancy'.
• Continuous methodological escalation for ultra-trace quantification has reached practical and operational limits.

Conclusions:

• The current approach to food safety testing faces practical and operational limitations.
• A transition towards adaptable, non-targeted chemical profiling using High-Resolution Mass Spectrometry (HRMS) is necessary.
• HRMS will enable proactive detection of emerging contaminants and food fraud in complex food matrices.
